What is the volume of a rectangular prism with the dimensions: base 2 3 8 cm, height 1 1 3 cm, and length 3 3 4 cm? A) 11 7 8 cm
shusha [124]

Answer:

The volume of the given prism is 11\frac{7}{8} cubic cm.

Step-by-step explanation:

Here, the dimensions of the given Prism is

Base  = 2\frac{3}{8} cm

Height  = 1\frac{1}{3} cm

Length  = 3\frac{3}{4} cm

Now. solving the given mixed fractions, we get

2\frac{3}{8} = 2 + \frac{3}{8}   = 2  + 0.375 = 2.375

1\frac{1}{3}= 1 + \frac{1}{3}   = 1  + 0.333 = 1.33

3\frac{3}{4} = 3 + \frac{3}{4}   = 3  + 0.75 = 3.75

Now, the given dimensions of the prism are :

B = 2.375 cm, H = 1.33 cm and L = 3. 75 cm

The VOLUME OF THE PRISM  = LENGTH x BASE x HEIGHT

                                                    =   2.375 cm x 1.33 cm x 3. 75 cm

                                                     =  11. 8453  cubic cm

Now,  11. 8453  = 11 + 0.845 = 11 + \frac{845}{1000}  = 11  + \frac{7}{8}   = 11\frac{7}{8}

Hence, the volume of the given prism is 11\frac{7}{8} cubic cm.

i need to know if any one can help me explain to my son how multi- step equations work like this ...8(8v-7)=12-4v​
Tanzania [10]

8(8v-7)=12-4v​

multiply the bracket by 8

(8)(8v)=64v

(8)(-7)=-56

64v-56=12-4v

move -4v to the other side

sign changes from -4v to +4v

64v+4v-56=12+4v

68v-56=12+4v-4v

68v-56=12

move -56 to the other side

sign changes from -56 to +56

68v-56+56=12+56

68v=12+56

68v=68

divide both sides by 68 to get v by itself

68v/68=68/68

cross out 68 and 68, divide by 68

then becomes 1*1*v=v

v=68/68

Divide the fraction by 68

68/68=1, 68/68=1

1*1=1

Answer:

v=1

IgorLugansk [536]
Given that t<span>he mean lifespan of a sylvania light bulb is 1600 hours with a standard deviation of 300 hours, an iqr of 450 hours, and a range of 690 hours. the lifespan distribution is relatively symmetric.

Since, the distribution is relatively symmetric, the measure of spread that is the best measurement is the standard deviation.</span>
